AC to DC 90 Watt Switching Power Adaptor Circuit AC to DC switching power adaptor circuit with maximum output power of 90W. Switching power supply is built using a high voltage power switching regulator IC MC33374 and some other additional components. The MC33374 IC is a monolithic high voltage power switching regulators that are specially [...]
Switch Mode Pre-Regulator Circuit The botheration was that a voltage regulator had to bead the 18 volt capital ability accumulation voltage to 8 volts at 500ma to ability the CD player, crumbling 5 watts of ability and causing a lot of calefaction central the bunched unit. This ambit acts as an interference-free pre-regulator to abundantly [...]
Latching Relay On/Off Switch Circuit The ambit beneath switches AC or DC ability to a amount application an ultra low ability 3v latching broadcast with two coils. The broadcast can handle about 10 amps of current, up to 250vac. Anniversary time the baby pushbutton is pressed, the ambit either latches the broadcast contacts bankrupt or [...]
High Speed µPs With 8A Switcher High Performance Circuit All high-current switchers are sensitive to board layout; take care when designing the pc board. You’ll obtain the best results by using a multilayer board, so you can dedicate a single layer to ground plane. You should tie the “power” components (C1, C2, C16, D2, C12, [...]
Figure 1. Substituting the diode-capacitor network shown for an inductor allows this switching-regulator IC to deliver 2mA at comparable line and load regulation, with somewhat reduced efficiency. Figure 2. Introducing a MOS driver (IC2) enables the Figure 1 circuit to deliver as much as 20mA. In conventional applications, switching-regulator ICs regulate VOUT by controlling the [...]
